Linus Torvalds fc02cb2b37 Core:
- Remove socket skb caches
 
  - Add a SO_RESERVE_MEM socket op to forward allocate buffer space
    and avoid memory accounting overhead on each message sent

    resolved by the kernel for use in acceleration paths (BPF / XDP
    right now, HW offload users will benefit as well)
